A patient safety system and method for delivering immersive multimedia and virtual reality content in a clinically safe and secure manner. The system and method for matching personalized virtual reality content with a user profile in a clinically safe and secure manner for the purpose of creating externally controlled immersive experiences during surgical procedures or medical treatments. Our invention takes personality type, anxiety levels, medical condition, procedural orientation, physical limitations, surgical complexity, duration of surgery, and content preference into account. Then it presents the content in a viewable headset interface that can be externally controlled by the healthcare provider for the safety of the patient. Both audio and visual communication are available between the healthcare provider and the patient to make the surgical procedure efficient for the healthcare provider and comfortable for the patient. Finally, the system matches preoperative and postsurgical content for the patient's benefit in preparation and recovery from the surgery.

A wearable computing device with bio-signal sensors and a feedback module provides an interactive mediated reality (“VR”) environment for a user. The bio-signal sensors receive bio-signal data (for example, brainwaves) from the user and include bio-signal sensors embedded in a display isolator, having a deformable surface, and having an electrode extendable to contact the user's skin. The wearable computing device further includes a processor to: present content in the VR environment via the feedback module; receive bio-signal data of the user from the bio-signal sensor; process the bio-signal data to determine user states of the user, including brain states, using a user profile; modify a parameter of the content in the VR environment in response to the user states of the user. The user receives feedback indicating the modification of the content via the feedback module.

A method of assessing inter-device communication pairing in a surgical setting, may include transmitting, by a first intelligent medical device, wireless communication data within the surgical setting, receiving, by a second intelligent medical device, the wireless communication data from the first intelligent medical device, determining, by the second intelligent medical device, communication pairing data indicative of an inter-device communication pairing of the second intelligent medical device with the first intelligent medical device, transmitting, by the second intelligent medical device, the communication pairing data to a modular control tower, and displaying, by the modular control tower on a display device, an augmented reality display comprising one or more virtual objects indicative of the inter-device communication pairing. An interactive surgical system may include multiple intelligent medical devices and displays which can form communication pairs in this manner.

Various embodiments of the present application set forth a computer-implemented method that includes detecting a tag that is associated with a real-world object, determining an object identifier (ID) associated with the tag, transmitting a request for data associated with the real-world object, wherein the request includes the object ID, receiving a set of values associated with the object ID from a data source, where the set of values is provided by the data source based on the object ID and on a query executed on raw machine data associated with the real-world object, and displaying, by a client device within the XR environment, a visualization associated with the set of values.

A handheld imaging device has a data receiver that is configured to receive reference encoded image data. The data includes reference code values, which are encoded by an external coding system. The reference code values represent reference gray levels, which are being selected using a reference grayscale display function that is based on perceptual non-linearity of human vision adapted at different light levels to spatial frequencies. The imaging device also has a data converter that is configured to access a code mapping between the reference code values and device-specific code values of the imaging device. The device-specific code values are configured to produce gray levels that are specific to the imaging device. Based on the code mapping, the data converter is configured to transcode the reference encoded image data into device-specific image data, which is encoded with the device-specific code values.

A method and system for color mapping digital visual content for improved viewing by a color vision deficient observer includes receiving the digital visual content to be color mapped, clustering color values of the digital visual content into a plurality of color clusters, assigning each color cluster to a respective one of a set of target color values in which the set of target color values have increased visual distinguishability for the color vision deficient observer; and for each color cluster, mapping the color values of the color cluster to the target color value, thereby generating a color-mapped digital visual content. One or more regions of interest of the content can be identified and the color mapping may be applied onto to those regions of interest.

According to various, but not necessarily all, embodiments there is provided an apparatus comprising means for binocularly displaying visual content as a first image directed towards a first eye of a user and as a second image directed towards a second eye of the user. The first image comprises a first area in which a blue spectral component of the visual content is reduced as compared to a corresponding first area of the second image. The second image comprises a second, different area in which a blue spectral component of the visual content is reduced as compared to a corresponding second area of the first image.

Described are various embodiments of a light field device and vision-based testing system using same. Different embodiments provide for a vision-based testing device comprising a one or more view zone optimization techniques such as, but not limited to, a predominant view zone isolator, a view zone output realignment solution, and a coarse view zone adjustment transfer solution, as well as other view zone artefact reduction techniques and multi-depth perception adjustment techniques.

A surgical instrument system comprising a handle, a shaft, and a disposable power module is disclosed. The handle comprises a motor, a control switch, and a motor-control processor which is in communication with the control switch. In various instances, the disposable power module comprises a disposable battery and a display unit configured to indicate at least one function of the surgical instrument system.

The disclosure relates to a medical device with a display and with a processing unit and method therefor. The processing unit is suitable for detecting states of one or more technical units of the medical device. The processing unit is further set up to control the display on the basis of detected states in order to output states of the medical device. The display is an autostereographic display. The processing unit, based on an evaluation of detected states, drives the display in such a way that a first state is visually highlighted with respect to a 3D representation, while a second state is visually not highlighted with respect to a 3D representation.
